This composition came to rise during Seasons 1 and 2, and remains extremely popular[citation needed]. It depends heavily on the Mage's "Shatter Combo" (a Frost Nova followed by a Frostbolt and Ice Lance), and the Shaman's burst ability. The name is based on the joke that the Shaman must only hit 4 buttons -- 2,3,4, and 5-- to kill an opposing player. The corresponding abilities are Heroism, a Lightning Bolt, a Nature's Swiftness instant Chain Lightning, and a Frost Shock. This composition's weakness largely lies in the lack of crowd control abilities (only the Mage has a silence and a spammable crowd control) and lasting power, primarily due to a Mage's more limited mana pool and inability to drain or regenerate mana as quickly.

A popular variant of this composition called 2346 is run with a Siphon Life/Soul Link or Felguard Warlock instead of a Mage

Later of in Wrath of the Lich King the composition of 2346 was run with a Destruction Warlock instead of a Mage
